Efficiency is measured as a ratio of the measured performance to the performance of an ideal machine: :$\backslash text\; =\; \backslash frac\}$ :$\backslash text\; =\; \backslash frac\}$ Because the power transmission system or mechanism does not generate power, its ideal performance occurs when the output power equals the input power, that is, when there are no losses. Real devices dissipate power through friction, part deformation and wear. The ideal transmission or mechanism has an efficiency of 100%, because there is no power loss. Real devices will have efficiencies less than 100% because rigid and frictionless systems do not exist. The power losses in a transmission or mechanism are eventually dissipated as heat. ==See also== * Mechanical advantage * Thermal efficiency * Electrical efficiency * Internal combustion engine * Electric motor * Velocity ratio 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mechanical efficiency」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
